Characterized by constant seismic and volcanic activity, the Pacific Ocean’s Ring of Fire is a vast horseshoe-shaped basin that sweeps over nearly 25,000 miles and includes more than 75% of the planet’s active and dormant volcanoes. Approximately 90% of the world’s earthquakes occur here, triggered by the volatile confluence of major tectonic plates in constant collision that exemplifies the dynamic nature of our planet.
Volcanologist Kirt Kempter leads a geologic overview of the Ring of Fire and an exploration of how relentless tectonic movements—including some of the Earth’s fastest-moving plates—drive earthquake and volcanic activity in hot spots such as Peru, New Zealand, Japan, and Alaska. Maps, diagrams, and Google Earth flyovers support geologic concepts and interpretations in the presentation.
